What is the purpose of a push rod in an engine?

A push rod transfers the motion from the camshaft's lifter to the rocker arm, which in turn opens the engine's valves. Proper length and straightness are crucial for correct valve timing and lift.

Why is the material and construction of push rods important?

Push rods handle significant forces during engine operation. Using strong materials like 4130 chrome moly and ensuring precise dimensions, like exact radii on the ends and close length control, helps prevent bending or failure and ensures consistent valve train operation.

What does the black oxide finish do?

The black oxide finish on these push rods provides a layer of protection against corrosion and wear. It also helps the push rod spin more smoothly within the rocker arm and lifter.

About this part

Product Details

If you're rebuilding the top end of your engine, these Manley push rods are a solid option. They're made from 4130 chrome moly tubing, which is a strong material for this application. Each push rod measures 7/16 inches in diameter with a 0.165-inch wall thickness and a length of 10.050 inches. This specific sizing is important for ensuring proper valve train geometry and lift.

Manley paid close attention to the ends of these push rods, forming them with exact radii for excellent concentricity. This means they'll spin true and maintain consistent contact with your lifters and rocker arms. They've also been heat-treated and finished with a black oxide coating, which helps with durability and corrosion resistance. This set includes eight push rods, enough for a typical V8 engine.
